I claim is 1- A storage battery tool comprising a pair of members pivotally united intermediate their ends, a aw having a sharp inturned edge formed on one of said members, said edge extending transversely of said member and being serrated, a flat recessed jaw formed on the remaining member and being longer than the first-mentioned jaw, and a heel formed on the serrated jaw.
